260 Transactions. — Botany. 



Obs. A species pretty closely allied to its small New Zea- 

 land congeners, H. depressa, Hook, fil., and H. mierantha, 

 Brown ; and also to some of the smaller Australian and Tas- 

 manian forms, but is abundantly distinct in many particulars. 



Genus 3. Gunnera, Linn. 

 1. Q.flavida, sp. nov. 



Plant glabrous, erect, 3-4 inches high ; leaves 7-9, radical, 

 membranous, broadly elliptic, f-1 inch long, margins siuuate- 

 crenulate, petioles 1-2 inches long. Scape erect, very stout, 

 much longer than leaves (about 4 inches), springing from root- 

 stock below leaves. Flowers not seen. Fruit in a spike (or 

 sub-raceme) 2 inches long, drupes fleshy, 1^—2 lines long, sub- 

 turbinate, compressed, patent, light yellow, scattered and pedi- 

 celled below, sub-sessile and pretty close together above. 



Hab. Swampy ground near Tahoraiti, County of Waipawa ; 

 April, 1885 : Mr. H. Hill. 



Obs. A species having some affinity with G. prorepens, 

 Hook, fil., but differing in several characters, as size and 

 form of leaves and petioles, length of scape, and position, 

 shape, and colour of ripe fruit ; which in G. prorepens are sessile, 

 very compact, and bright-red. I have received, through the 

 kindness and courtesy of Mr. Hill, several good and whole 

 specimens, and they do not vary. 



Order XXXIII. UMBELLIFEE.E. 

 Genus 1. Hydrocotyle, Linn. 

 1. H. colorata, sp. nov. 



Plant hirsutely-pilose ; stems stoutish, 1-2 feet long, creeping, 

 rooting at nodes 1-2 inches apart, usually one leaf and one 

 peduncle bearing flowers from each node. Leaves pale-green, 

 often purple- margined, soft, rough above with muricated points 

 and white sub-succulent strigillose hairs, 8-10 lines diameter, 

 orbicnlar-reniform with a very broad sinus, 7-veined, 5-lobed 

 (the two outer lobes being larger and sub-lobed), lobes cut ^rd 

 to middle, each acutely and many toothed ; petioles very long, 

 3-5 inches ; stipules rather large, membranous, shining, coloured 

 pink, sharply laciniate. Flowers : peduncles f-1 inch ; heads 

 small, globular, many-flowered, 15-30; petals broadly-ovate, 

 acute and concave, whitish-yellow streaked with red on the 

 outside, pinkish within, very shortly pedicelled : bracteoles 

 small, linear-spathulate, obtuse, appearing above flower-buds 

 and covering them before expansion, and persistent. Fruit very 

 small, y 1 ^ inch diameter, glabrous, chestnut-brown ; styles distant, 

 much recurved ; carpels somewhat turgid, with a narrow ridged 

 rib on each face; back acutely ridged: dark-brown when fully 

 ripe, persistent.
